The Treaty of Guadalupe Hidalgo specified the major consequence of the war: the forced Mexican Cession of the territories of Alta California and New Mexico
to the U.S. in exchange for $15 million. In addition, the United States
forgave $3.5 million of debt owed by the Mexican government to U.S.
citizens. Mexico accepted the loss of Texas and thereafter cited the Rio Grande as its national border.

In Mexico, terminology for the war include (primera) intervención estadounidense en México (United States' (First) Intervention in Mexico), invasión estadounidense a México (The United States' Invasion of Mexico), and guerra del 47 (The War of 1847).
